This is Company 23's Anti-Surge Boost Control Solenoid. It will eliminate the common internal and external wastegate flutter thus providing the driver with a consistent, yet a very strong boost curve.

Compared to other 3-port boost control solenoids, the main feature in the Company 23 Anti-Surge unit is that it eliminates wastegate flutter. It prevents oscillation in the boost curve, and it makes more horsepower and torque when compared to a detuned map that is focused on eliminating flutter. 

When compared to manual style boost controllers, the Company 23 Anti-Surge unit will allow RPM/load dependent boost control. You won’t have to worry about partial throttle/full boost during closed loop, and it does not require retuning for temperature or seasonal changes, or even changes in elevation.
